Description

Technical Field

[0001] This utility model relates to the technical field of ceramic processing equipment, specifically a surface trimming device for ceramic handicrafts. Background Technology

[0002] In the production of ceramic handicrafts, after the blank is formed, a surface trimming process (i.e., trimming) is usually required to remove excess burrs, air bubbles, or deformed areas, ensuring a smooth surface, accurate contours, and meeting the quality requirements before glazing or decoration. Traditional trimming methods rely heavily on manual operation, often using hand-held trimming knives or simple rotating tables. While this method is simple in structure, it is labor-intensive, the processing accuracy is significantly affected by human factors, it is difficult to guarantee the shape consistency of complex curved surfaces, and the trimming efficiency is low, easily causing damage to the ceramic blank or increasing the scrap rate.

[0003] To improve trimming efficiency, some semi-automatic trimming devices have emerged in the existing technology, such as trimming tables driven by single-axis motors or cutter mechanisms with adjustable supports. However, these devices are mostly single-degree-of-freedom motion structures, meaning the trimming cutter head can only be adjusted in a single direction or at a fixed angle, making it difficult to adapt to the trimming needs of ceramic blanks of different sizes and shapes. In addition, some devices are bulky, have poor overall rigidity, and involve complex cutter replacements, limiting their flexible use in different process scenarios.

[0004] In view of this, we have studied and improved the existing problems to provide a ceramic craft surface trimming device to solve the current problems. The aim of this technology is to solve the problems and improve the practical value. Utility Model Content

[0005] This invention aims to solve the problems of existing ceramic trimming devices, such as simple structure, inconvenient adjustment, low trimming accuracy, and inability to quickly adapt to different sized ceramic blanks. It proposes a ceramic craft surface trimming device with a simple structure, precise positioning, and rapid assembly. Through the coordinated design of a multi-axis control component and a quick-release tool mechanism, this device achieves multi-directional precision movement of the trimming tool head and detachable combination operation, thereby effectively improving the trimming accuracy, assembly efficiency, and application flexibility of ceramic blanks.

[0006] This utility model provides a ceramic craft surface trimming device, including a base, a trimming turntable, a multi-axis control assembly, and a trimming cutter head. The base is an integral support structure, and the trimming turntable is set above the base to support the ceramic blank to be trimmed and is driven by a drive motor to rotate. The multi-axis control assembly is set in the side area above the base to realize bidirectional linkage control of the trimming cutter head. The trimming cutter head is mounted on the surface of the quick-release cutter holder on the moving sleeve base and is used to cut and trim the surface of the rotating ceramic blank.

[0007] The device is compact, precise in motion, and easy to operate. It can achieve multi-angle trimming of the ceramic blank surface through multi-axis collaborative control, and has strong adaptability and maintainability.

[0008] In a preferred example, the base adopts an integral welded structure, with a drive motor embedded in its upper surface to drive the rotation of the trimming turntable. The trimming turntable has a smooth disc-shaped structure with annular positioning grooves on its surface to fix the position of the clay blank during the trimming process and ensure its concentric rotation.

[0009] Specifically, the combination design of a smooth mirror turntable and positioning groove can stably support ceramic blanks of different sizes, ensuring that the blanks maintain a constant posture during rotation, thereby improving the coaxiality and surface uniformity of the finishing process.

[0010] In a preferred example, the multi-axis control assembly includes a vertical column assembly and a horizontal column assembly, both arranged vertically, for controlling the movement of the trimming cutter head in the vertical and horizontal directions. Both the vertical column assembly and the horizontal column assembly are equipped with a guide rod, a lead screw, and a drive motor. The guide rod provides linear guidance, and the lead screw is connected to the motor output to achieve precision feed.

[0011] Specifically, through bidirectional lead screw drive and sliding guide rod guidance, precise positioning can be achieved in two coordinate directions, meeting the trimming needs of different heights and widths of the ceramic blank and improving processing flexibility.

[0012] In a preferred example, the movable sleeve is slidably sleeved on the surfaces of the upright group and the crossbar group. It has a sliding sleeve hole and a screw sleeve hole arranged perpendicularly to each other inside, which are used to guide the movement of the sliding guide rod and the lead screw, respectively, so as to realize the bidirectional translation of the movable sleeve in the spatial coordinate system.

[0013] Specifically, this structure enables the trimming cutter head to move synchronously or independently in two directions, achieving high-precision and controllable multi-trim trimming paths, suitable for precision trimming of ceramic blanks with different curved surfaces and shapes.

[0014] In a preferred example, one end of the crossbar assembly is provided with a quick-release blade holder, the surface of which has a quick-connect mechanism adapted to the end of the trimming blade head, and the trimming blade head can be quickly installed and removed by a locking mechanism.

[0015] Specifically, the quick-release tool holder allows for tool replacement without disassembling the overall structure, significantly improving operational efficiency and facilitating the selection of different types of tools for dressing at different process stages.

[0016] In a preferred example, the base has detachable cable structures on both sides, with the top of the cable fixedly connected to the top of the upright assembly. The cable is made of high-strength steel wire rope and remains taut during device operation.

[0017] Specifically, the cables provide lateral support, which can effectively prevent the pole assembly from swaying under motor start-stop and cutting loads, thereby improving the overall structural stability and trimming accuracy.

[0018] In a preferred example, the surface of the sliding guide rod is provided with a wear-resistant lubricating coating to reduce the frictional resistance of the moving sleeve during sliding and reduce wear.

[0019] Specifically, the lubrication layer ensures smooth operation of the sliding structure, extends the service life of the lead screw and sliding components, and guarantees the reliability of the equipment during long-term operation.

[0020] In a preferred example, both the upright and horizontal bar motors are controlled by stepper motors, and multi-axis synchronous drive and displacement compensation are achieved through a numerical control module.

[0021] Specifically, through precise control by a stepper motor, the multi-axis linkage motion of the trimming cutter head can be realized, resulting in a continuous and stable trimming trajectory and high trimming accuracy.

[0022] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the combination design of the base, the trimming turntable and the multi-axis control components enables the trimming cutter head to move precisely in both vertical and horizontal directions. The structure is simple and the control is flexible. It can be adapted to ceramic crafts of different sizes and shapes, and can achieve fine surface trimming and edge shaping, significantly improving trimming accuracy and processing efficiency.

[0023] 2. In this utility model, the multi-axis control component adopts a detachable assembly structure. The upright group and the crossbar group are slidably connected through the moving sleeve seat. The quick-release tool holder realizes the quick replacement of the blank trimming tool head. The whole assembly and disassembly are convenient. It can be quickly installed and reused in different operating tables or production lines, improving the adaptability of the equipment to application scenarios and maintenance efficiency.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of a ceramic craft surface trimming device provided by this utility model.

[0029] Combination Figures 1-4 As shown, the present invention provides a ceramic craft surface trimming device, including a base 100, a trimming turntable 110, a cable 120, a multi-axis control component 200, and a trimming cutter head 300.

[0030] The base 100 supports the entire device structure, and a drive motor for driving the rotation of the trimming turntable 110 is embedded in its upper surface. The trimming turntable 110 has a disc-shaped structure, and its surface is provided with a smooth mirror layer and an annular positioning groove for fixing the ceramic blank and keeping the blank in a stable position during rotation.

[0031] In this embodiment, the base 100 is detachably equipped with cables 120 on both sides. The upper end of the cables 120 is fixedly connected to the top of the pole assembly 210. The cables are rigid rope structures and are in a tensioned state. They are used to assist in supporting the pole assembly 210 and prevent it from shaking during operation, thereby improving the overall stability and accuracy of the system.

[0032] like Figure 2 As shown, the multi-axis control assembly 200 includes a vertical rod assembly 210, a horizontal rod assembly 220, a movable sleeve seat 230, and a quick-release tool holder 240.

[0033] The upright rod group 210 and the horizontal rod group 220 are arranged perpendicularly to each other, and are used to realize the movement control of the trimming cutter head 300 in the vertical and horizontal directions, respectively.

[0034] In this embodiment, both the upright assembly 210 and the crossbar assembly 220 consist of a sliding guide rod 211, a lead screw 212, and a motor 213. The sliding guide rod 211 is symmetrically arranged on both sides of the lead screw 212, with one end fixedly connected to the output end of the motor 213. The motor 213 drives the lead screw 212 to rotate, thereby causing the moving sleeve 230, which is threadedly connected to it, to move precisely along the direction of the lead screw, realizing the displacement control of the trimming cutter head 300 in different axes.

[0035] like Figure 3 As shown, the movable sleeve 230 is slidably sleeved on the surface of the upright assembly 210 and the crossbar assembly 220, and has two sets of mutually perpendicular sliding sleeve holes 231 and threaded sleeve holes 232 inside.

[0036] The sliding sleeve hole 231 is used to guide the linear movement of the sliding guide rod 211; the threaded sleeve hole 232 has a threaded structure that matches the lead screw 212. After threaded engagement with the lead screw 212, the moving sleeve seat 230 can achieve synchronous sliding control in two directions. By guiding the movement of the sliding guide rod 211 and the lead screw 212 respectively, this dual-axis structure design allows the moving sleeve seat to achieve high-precision translational movement in both vertical and horizontal directions.

[0037] In this embodiment, the surface of the sliding guide rod 211 is provided with a wear-resistant lubricating coating to reduce the frictional resistance of the moving sleeve seat 230 during the sliding process, ensure the smoothness and durability of its movement, and improve the overall service life.

[0038] like Figure 4 As shown, one end of the crossbar assembly 220 is fixedly connected to a quick-release blade holder 240, the surface of which is provided with a quick-connect structure adapted to the end of the trimming blade head 300. The trimming blade head 300 can be quickly installed and removed through this quick-release structure, allowing the operator to change blades according to different shapes and sizes of ceramic blanks, thereby adapting to different trimming needs.

[0039] A fixing seat is provided at the bottom of the upright assembly 210. The fixing seat is sleeved on the surface of the sliding guide rod 211 and inserted into the surface of the base 100. This design allows the upright assembly 210 to be quickly assembled and disassembled, facilitating transportation and maintenance.

[0040] Working principle and usage process of this utility model: When in use, the operator first places the ceramic blank to be repaired on the surface of the repair turntable 110 and starts the drive motor in the base 100 so that the repair turntable 110 rotates smoothly at the set speed.

[0041] Subsequently, the motor 213 in the multi-axis control assembly 200 is activated, driving the lead screw 212 to rotate. Through the threaded engagement with the inner threaded hole 232 of the moving sleeve 230, the moving sleeve 230 can move precisely in both directions along the upright assembly 210 and the crossbar assembly 220. The trimming cutter head 300 is fixedly mounted on the moving sleeve 230 via a quick-release cutter holder 240, and its position can be adjusted horizontally and vertically along with the moving sleeve.

[0042] During the trimming process, the operator precisely adjusts the radial and axial positions of the trimming cutter head 300 according to the curvature and dimensional requirements of the ceramic blank surface through the synchronous control of the motor 213, so that the cutter head gradually cuts or scrapes the surface of the ceramic blank along the rotation path of the turntable. The bidirectional sliding structure of the moving sleeve 230 enables the trimming cutter head to continuously trim complex curved surfaces, ensuring that the surface of the ceramic blank is smooth and the dimensions are accurate.

[0043] After finishing, the operator can quickly disassemble the finishing cutter head 300 or replace it with different specifications of cutters to adapt to other craft shapes. The entire operation process is stable and reliable. With the tensioning support structure of the cable 120, the vertical stability and finishing accuracy of the upright assembly 210 are effectively guaranteed.
